鄱阳湖入湖径流和水资源变化特征分析

Characteristic Analysis of Inflow and Water Resources in the Poyang Lake Basin

摘要: 鄱阳湖流域占江西省国土总面积的97.2%，占长江控制流域面积的9%，鄱阳湖流域水资源变化对长江流域有着显著影响。本文通过分析鄱阳湖流域降水、径流等水文水资源要素，得出了各要素的年际、年内及地域空间上的变化规律。同时，采用Mann-Kendall (MK)方法，分析鄱阳湖流域隆水量以及各站年入湖径流的变化趋势。

Abstract: Poyang Lake basin accounts for 97.2% of total land area in Jiangxi Province and 9% of Yangtze River basin, and the change of water resources in the Poyang Lake significantly affects Yangtze River drainage area. In this study, the inter-annual, intra-annual and regional variation rules of each element were obtained through analyzing precipitation, runoff and other elements of hydrology and water resources in the Poyang Lake basin. Meanwhile, the Mann-Kendall (MK) method was used to analyze the precipitation of the Poyang Lake basin and the significance level of variation trend of annual inflow in each station.
